Construcción de una herramienta neumática para compresión de muelles de válvulas adaptable a diferentes tipos de fijadores

Abstract

This work aimed to build a pneumatic tool for the valve spring compression adaptable to different types of fasteners. There were analyzed the geometric characteristics of gasoline and diesel engines heads, the mechanical properties of materials to be used, the necessary pressure for spring compression. It was obtained by a compression test. The technical characteristics were analyzed through a bibliographic review. The required working pressure was 6 to 10 bar. The design of machine tools allowed it to analyze and choose the appropriate materials for the construction of the tool. Previously considering the design of the pneumatic circuit using the FESTO software, the modeling using SOLIDWORKS software, and its structural analysis using ANSYS software WORKBECH. These considerations allow adaptability to the different geometries of the valve spring fasteners, valve travel, and head geometry in engines gasoline and diesel complying with Directive 2006/42/CE, the regulation that establishes that machines must meet essential health and safety requirements. It is considered required parameters by the operator, user, designer to design thetool, allowing it to fulfill an efficient and effective performance at the time of fulfilling its function, being a useful tool in workshops and automotive companies dedicated to the maintenance and motor repair. It is concluded that the pneumatic tool dueto. its simplicity reduces operating time of 60 to 70% during valve assembly and disassembly, complies with the adaptability to different existing fixators. It is recommended to consider the simplicity of the tool for its quick and correct use must meet minimum safety parameters, operation, health, and safety as well as mechanical aspects that it may suffer and for which it must anticipate in the simulation and analysis of the results obtained.
